LOOM-SHUTTLE.

SPECIFICATION forming part of Letters Patent N0. 691,607, dated January 21, 1902.

Application filed September 25, 1901. Serial No. 76,462. (No model.)

T all whom t may concern:

Be it known that we, EDWARD W. DAVEN- PORT and HENRY BARDsLEY, citizens of the United States, residing at Providence, in the county of Providence, State of Rhode Island,

have invented a certain new and useful Improvement in Loom-Shuttles, of which the following is a specification, reference being had therein to the accompanying drawings.

ro The invention relates to the devices which are employed in loom-shuttles for the purpose of ascertaining when the yarn-load which is carried by the working shuttle of a loom has become exhausted or depleted to the prede- I 5 termined extent and for the further purpose of calling into action instrumentalities for bringing about a prearranged change in the working of the loom.

The inventionconsists in improved devices zo of the said class, and rst will be described with reference to the drawings, in which latter is represented an embodiment of the invention, after which the characteristic and essential features thereof will be particularlyT pointed out, and distinctly defined in the claims at the close of this specification.

In the drawings, Figure l shows, mainly in horizontal section, a portion of a loom-shuttle having the said embodiment of the invention 3o applied thereto. Fig.2shows the saine,mainly in vertical section. Fig. 3 shows the same in transverse vertical section on the plane indicated by the dotted line 8 3, Fig. l.

Having reference to the drawings, l desig- 3 5 nates the body of a loom-shuttle.

2 is a shuttle-spindle pivoted within the shuttle'- body upon a transverse pin 3, as usual.'

et is the usual spindle-actuating spring,

4o makingcontact with the head of the spindle 2.

5 is a bobbin-catch applied to the heel 2l of the spindle, as customary, and 6 is the disengaging pin by means of which the bobbincatch 5 is held back when the tip of the spindle is raised, thereby disengaging the said bobbin-catch from the groove 7l in the head of the bobbin 7, mounted upon the spindle.

In general the foregoing parts are or may be as heretofore or as preferred.

In conformity with our invention we apply 5o to the shuttle spindle 2 a movable feeler, which is operated through the agency of a spring tending to move the feeler transversely of the spindle. Inv applying a yardload to the shuttle spindle the said yarn -load is 5 5 caused to inclose or surround the feeler. By means of the yarn-load, which is placed exterior to the spindle and feeler, so as to surround them, the said feeler is confined in an abnormal position. So soon, however, as the 6o said yarn-load becomes unwound and drawn ed in the operation of weaving sufliciently far to leave the feeler free to move, the said feeler is operated by a spring and caused to assume its normal or operative position. It is intended that the said feeler in the normal or operative position thereof shall coact with or control outside instrumentalities for bringf f ing about the desired results in the working of the loom in which a shuttleembodying the 7o invention is employed. Thus, as will be 0bvious to those who are skilled in the art, the said feeler may be utilized to bring about an arrest of the action of the whole or s ome part of the loom mechanism or to bring about automatic replenishment of the working weft supply, all substantially as heretofore proposed in the art. The said outside instrumentalities and the precise manner of the co operation of the trip therewith are not mate- 8o rial to our invention, which resides more especially in the shuttle and its parts. The construction and 'arrangement of the feeler and coacting parts may vary somewhat in practice. 8 5

A movable feeler, such as that which is referred to above, is shown at 8. It is shown connected with the shuttle-spind1e2by means` of a pivot-pin 9, arranged near the inner end of the feeler. The feeler swings radially with go respect to the shuttle-spindle upon said pivotpin. Preferably, although not necessarily, in all embodiments of the invention the feeler is mounted in posit-ion to swing transversely caused to act against the inner portion of the wardly into contact with the coils ot' yarn of the shuttle, as shown. Preferably, also, l the shuttle-spindle is formed with a slot 2l, extending longitudinally thereof, within which slot the feeler is litted and works. Thereby the feeler is protected or shielded and steadied in its working. When a yarnload is applied to the shuttle-spindle, whether such yarn-load is contained upon a bobbin or not, lthe working arm of the t'eeler is inserted into the central opening of said yarn-load together with the sh Little-spindle. For the purpose of causing the working arm of the pivoted feeler to press outwardly against the portion of the yarn-load which surrounds the same a spring-actuated presser or plunger is feeler. The said presser-plunger is arranged to move longitudinall7 of the shuttle-spindle. Such a presser or plunger is shown at l0. It preferably is contained within a passage formed in the shuttle-spindle and extending longitudinally of the latter. The head of the presser or plunger bears against the camshaped edge of the inner arm of the feeler. The actuating-spring l2 occupies the said passage, said spring surrounding the stem of the presser or plunger and being compressed bel tween the rear shoulder ot the head ofthe latter and the inner end ot' the screw 13. The y said screw is iitted to the outer end of the 5 passage ll and is hollow to receive and guide i the stein ot' the presser or plunger.

For the purpose of automatically closing the working arm of the feeler into line with the shuttle-spindle when the latter is raised, l and thereby facilitating the application of a l yarn-load to the spindle or the removal of the l same from the latter, we provide a closingcam l-l. (See more especially Fig. 3.) The said cam It is applied to an interior wall of the shuttle-body adjacent the pivot of the shuttle-spindle and is provided with an acting face which is shaped and arranged, as shown, so that in the depressed and horizontal position of the shuttle-spindle the feeler is free of the cam and subject to the control of its springactuated presser or plunger, while as the shuttle-spindle is raised into its outturned position the tail or heel of the feeler is acted upon by the said acting face of the closing-cam Maand thereby the feeler is swung into line with the axis of the spindle.

In the case of using yarn which is wound upon bobbins each bobbin 7 is formed with a slot 72 through one side thereof,within which the working arm of the feeler may enter and through which slot said arm may swing outwhich are wound upon the exterior of the bobbin. For the purpose of preventing the bobbin from turning upon the shuttle-spindle, so as to cause a wall of the slot 72 to bind against the feeler S and impede or prevent the movement thereof, we provide a bobbinl positioning device l5, constituted by a bent spring-strip having its yielding free extremity provided with a projection 151, which enters the slot 72.

In the case of the illustrated embodiment of our invention it is contemplated that the working arm of the feeler when the feeler is released by the drawing off of the coils of yarn conlining the same shall project through a slot 16 in one wall of the shuttle-body, so that its end may engage with the exterior instrumentalities, to which reference is made at the outset hereof.
